This invention relates to an improvement in coin collecting means fortelephone services and the like, and the objects of the in vention areto provide a simple reliable mechanism by which coins of variousdenominations may be received and held temporarily while the necessaryelectrical connections are made and then be either cashed in orreturned.

Other objects are to provide a mechanism which may be installed andoperated without substantially adding to the existing tele-.

H hold coins and to move them to discharge or cashing in position, anelectromagnetic control device connected to the projecting memher, powermechanism, and timing means connected to the coin projecting member ashereinafter described. Various auxiliary devices may also be provided toprevent improper operations ot the machine and to regulate andsynchronize the operation of the various moving parts.

The mechanism is hereinafter fully described in the accompanyingspecifications and drawings.

The drawings show an apparatus embodying one form of the invention.

In the drawings, Fig. 1 is a sectional front elevation. Fig. 2 is afragmentary sectional front elevation showing the parts in a diiierentposition to that oi 1. 3 is a sectional front elevation showing adifferent arrangement of the parts to that shown in F 1. Fig. t is asectional detail of a portion of the coin projector. Fig. 5 is asectional elevation showing the delayed control mechanism Fig. 6 is asectional end elevation. Fig. 7 is a sectional rear elevation.

Serial No. 154,819.

Fig. 8 is a circuit diagram showing appropriate electrical connectionsfor the use of the device.

in the drawings, 10 indicates a suitable casing in which the workingparts are operatively mounted on a frame 11 which may be connected tothe casing in any suitable way, conveniently in such a manner that theframe and mechanism mounted thereon may be swung out of the casing forinspection or repair. I accomplish this in the n'ieehanism illustratedby the provision of supporting brackets 12 on the frame having pins 13engaging suitable perforations in lugs 14: on a bracket 15 secured tothe casing.

The casing 10 is formed with an opening 16 through which the coin maypass to one or more coin slots 17 ot the size and shape of the coin ofthe desired denomination, and located above coin chutes or carriers A, Aand A The coin chutes A, A and A may be provided with suitable means fordetecting false or spurious coins, such means not, however, forming partof the present invention. The form of these means which I haveillustrated are those shown in my British Patent No. 2-t3080 of the 23rdAugust, 1924.

The coin or coins are designed to pass down the coin chutes or carriersA, A and A under the action of gravity until they are received by thecoin projector B which is pivotally or reciprocably mounted on the frameand designed to return by gravity to a given normal position, or to beheld in an unbalanced position by the mechanism hereinafter described.

The coin projector B is provided with a number of compartments l8, l9and corresponding in number to the coin chutes and having open lowerends through which the coins may be projected or discharged under thecontrol of the electromagnetic control mechanism C.

In the receiving position of the coin projector B the passage of thecoins through the open lower end of the compartments 19 and 20 isnormally prevented by a balanced coin holder D which is conveniently inthe form. of a lever pivotally mounted in a bracket 21 on the framehaving a balance weight 22 at one end and a projection 23 at the otherend Which extends transversely across he lower end of the compartments19 and 20 when the coin projector B is in receiving position. In thisposition a fixed pin or other projection 24 mounted on the frame isdesignedto extend across the lower end of the compartment 18. In thisway the coins in the compart ments 19 and 20 are held against a balanceweight, while the coin in the compartment 18, if such there be, will beheld by the pin 2 l.

The electromagnetic control device G is operatively connected to thecoin projector 1') through a spring detent mechanism including a springlatch 25 operativcly mounted on the frame actuated by tension spring 26extending between one end of the latch and a fixed pin 27 on the frame,the latch being designed to engage a tooth or projection 28 on the coinprojector B and to be disengage: therefrom by operation of the pivotedarmature'29, one end of which, when the magnet 30- is energized, isdesigned to engage a pin 31' on the latch.

The magnet 30 may include one or more coils and be supported by asuitable bracket 32 connected to the frame. It will be observed that theextension of the armature 29 and its connection with the pin 31 adjacentto the pivotal point of the latch 25, enables a small movemcntof thearmature 29 to cause a relatively large movement of the end of tee latchwith which it is engaged with the tooth or projection 28. In this waythe maximum power can be obtained from the magnet by location of thearmature 29 adjacent thereto.

The coin projector B may be moved from thcreceiving position shown inFig. 3 either tothe discharge position shown in Fig. 1 or to the cashingin position shown in Fig. 2. Wdien moved to the cashing in position thecompartments 18, 19 and 20 passing away from the projections 23 and 24:leave thecoin free to pass down the fixed chute 33 to the collectingreceptacle 34:. In a similar way when the coin projector is moved to thedischarge position shown in Fig. 1 the coins may pass down a chute 35 tothe discharge chute 3'6 whence tl o may be withdrawn by the personoperating the device.

To prevent tampering with the mechanism by insertion of a wire or thelike through the discharge chute 36, I conveniently provide a pivotedbaffle plate 87 designed to swing by gravity into a position to closethe chute 35 and to be moved from such position by the coinprojector Bwhich is designed to engage a pin 38 on the baffle plate 37.

The energy for the operation of the coin projector or for its movement.to an unbalanced position may be derived either from the movement of thereceiver of the telephone to which the mechanism is applied or by anappropriate mechanism actuated by the open ator through the insertion ofthe coin or otherwise. The mechanism presently illustrated uses both ofthese means.

The energy derived from the movement of the telephone switch or receiverhook 89 is stored and applied to the coin chute B through the mechanismindicated generally by the letter F and including a lever 40 connectedto the receiver hook. Pivoted to the casing 10 and mounted on thepivoted pin all about which the lever 40 turns is a bell crank lever 42having one end rested against a stop pin 42 and having a relativelystrong tension spring 43 extending from a pin H on the arm to a pin 4-5on the lever 10. A furthcr spring 16 may be provided extending betweenthe pin 45 and a fixed pin 47 on' cas- In order to give time for thecompletion of the necessary electrical circuits and for other purposes atiming or governing mechanism G is into posed between the energizingmechanism F and the coin projector B. This timing mechanism may be ofany convenient form designed to produce delayed action and I show it inthe form of an escapcinent mechanism having an cscapemont wheel 48mounted on a bracket 19 on a frame 11 being engaged by an escapemcnttooth or part 50 pivotally mounted and connected to 21- dependingbalance arm 51 which is conveniently screw threaded and has a balanceweight 52 mounted thereon in screw threaded engagement therewith.

Ti lie escapement wheel 28 has a pinion 53 connected thereto meshingwith a gear 54 also mounted on a frame 49 whichlatter gear turns with apinion 55 meshing with a gear 56 also mounted on the frame 49. The gear56 carries a ratchet wheel 57 which is engaged by spring staggered pawls58 and 58 pivotaclly mount d arried by a pin 59 on a plate 60 v nichplate is adjustably connected to a control quadrant or cam 61 whichisloosely pivoted on the pin 62 on whichthe ratchet 57 and cam 56 arealso mounted.

The connection between the plate 60 and the quadrant 61 is madeadjustableby means of crmnecting set screw 63 which extends through aslot 6% in the plate 60 into the quadrant 61.

The quadrant 61 is designed to be returned to a normal position whenremoved therefrom by means of a tension spring 65 extending from a pin66 on the quadrant to a fixed pin (37 on the frame 11.. i

Connection is effected between the energizing mechanism F and the timingmechanism G by means of a pin 68 fixed to the quadrant 61 and designedto be engaged by the lower extremity of the lever 42.

The motion of the quadrant 61 is in turn communicated to the coinprojector B by a link 68 pivotally connected to the quadrant and havinga slotted end 69 through which a pin 70 on. the coin projector Bextends, the

m ns

pin being conveniently screw threaded and provided with a retaining nut71. The pin is designed to slide freely in the slot 69.

The quadrant 61 during its motion is designed to make and break certainelectrical connections and this may be accomplished by means of a springcontact finger 72 mounted with suitable insulation on a supportingbracket 73 on the frame and having at its outer extremity a roller 741engaging a cam;

surface or track 75 on the quadrant 61. The finger T2 is disposedbetween two contact fingers '76 and '77 placed a short distance on eachside thereof and themselves supported by and insulated from the bracket73.

lin order to prevent insertion of coins when the coin projector B is notin its proper receiving position I provide locking mecha nism Hincluding a lever 7 8 pivoted to a pin 7 9 on frame and having atransversely projecting pin designed in a certain position to extendacross the coin slots.

The lever 78 is connected to and moves with a quadrant 81 also pivotallymounted on' the pin 79 and formed with a cam face or surface designed tobe engaged by a pin 83 mounted on an arm 84 of the coin projector B.

A further connection is formed between the quadrant 81 and the arm 84 bymeans of an arm 85 on the quadrant which is provided at its extremitywith a pivoted link 86 having a slotted end 87 in which the pin 88 onthe arm 8 loperates. The quadrant 81 in its movement is designed to makeand break certain electrical. connections by means of a spring finger 89mounted on but insulated from bracket 90 on the frame, the finger 89being engaged at an appropriate moment by an insulated pin 91 on thequadrant 81 and being designed during its movement to make contact withone or more additional contact fingers 92 supported on but insulatedfrom the bracket 90.

The balanced coin holder D may also be used to make or break certain ofthe electrical connections by means of an arm 93 carried by and movingwith the lever D which is designed during its movement to engage aspring contact finger 94 which may also be supported on and insulatedfrom the bracket 90, this contact finger being designed to cooperatewith other fixed contact fingers 95 and 96 located on opposite sidestherefrom, its normal position being in contact with the finger 95.

The electrical connections to the various contact fingers on the frame11 are preferably made through the means of fixed studs 97 mounted on aterminal plate 98 and designed when the frame is in its innermostposition to engage with cor-responding spring contact fingers 99.

The passage of coin through the coin chute may be audibly indicated tothe operator by any well-known suitable means such as the microphone 100placed adjacent to a bell 101 designed to be struck by the coin duringits movement. A separate gong 102 may be provided for the chute 18 whichconveniently may be used for coins of larger denominations.

A typical operation of the device is as follows The normal position ofthe parts is as shown in Fig. 1 in which position the telephone receiveris on the hook 39 and the coin projector B is held in an unbalancedposition by the engagement of the pin 68 with the lever 42.

The coin slots are closed by the pin 80 and the quadrant 81 is locked byengagement of the pin 83 with the cam surface 82 thus preventingdisplacement of the pin 80.

The electrical circuits may considerably vary to suit the character ofthe telephone system with which the device is to be used.

.A typical circuit for use in automatic telephony is indicated in Fig. 8in which the electromagnet 30, quadrant 61, spring finger 72 and contactfingers 76 and 7 7 indicate the mechanical parts previously referred to.

The contact finger 77 is connected through the electromagnet 30 to theground. The contact finger 72 is normally in contact with the contactfinger 77.

Reference character a indicates the usual two wire line circuitextending to the exchange, one side of the circuit being connectedthrough the usual line switch Z) to ground and the opposite side beingconnected through the line switch 0 and battery (Z to ground.

An automatic dialling device 6 is included in one side of the line andthe usual bell or signal device 7 is connected across the line through acondenser g.

The contact fingers 94 and 95 when engaged, as they are in the normalposition shown in Fig. 1, form a short circuit about the dial 6.

The contacts 89 and 92 are designed to form a short circuit above thetelephone instrument to prevent fraud as hereinafter described.

In order to operate the magnet 30 at the appropriate moment means areprovided for sending an impulse over one side of the line and I find itconvenient to utilize in the automatic system the metering means at thecentral station and have indicated such means by the contacts h and 2',meter j and battery 70 one side of which is connected to ground. In thisway when the metering circuit is closed an impulse from the battery 70will be sent over the line to the magnet 30 as hereinafter more fullydescribed.

Returning to the mechanical parts in their normal position as shown inFig. 1 and assuming that it is desired to make a telephone call, thecaller first takes the telephone receiver K off the hook 39 which movesthe arm 12 out of engagement with the pin 68, thereby releasing the coinprojector permitting it to swing to the receiving position indicated inFig, 3, inwhich position it is held by engagement of the latch 25 withthe projection 28. At the same time the engagement of the pin 83 withthe cam surface 82 releases the quadrant 81 and leaves the pin 80 freeto be moved by the coin. V

The coin or coins being inserted through the coin slots pass down thecoin chutes into one or bothot' the compartments 18 and 19 being, heldat the bottom of the compartments by the projecting arm 23 on thebalanced coin holder D.

If the coins are of the proper weight they will depress the balance coinholder D causing, the movement of the contact finger 9a which will.break contact with the finger 95 and thereby break the short circuitabout the dial. 6 permitting the sending ot the dialling impulsesby thecaller. Thisthe caller proceeds to do either completing the call in theusual way or obtaining a busy signal or other wise. failing to obtainthe connection.

Assuming in the first place thatthe call is effective the callerreplaces or hangs up the receiver K after completing his conversation.This returns the lever 40 to its originalposition, energizing thesprings 43 and and tending to cause movement of the lever 42 whichmovement is delayedby the action of the timingmechanism G. The lever 4-2sets inmotion the quadrant 61 and the timing mechanism. Gr, and duringthe movement of the quadrant61. the contact finger 72 by operation ofthe cam 7 5. breaks contact with th finger 76and'makes contact with thefinger 77 thereby connecting the electromagnet 30 to one side of theline, first breaking the line by disengagement ofthe contact 76 with thecontact finger 72'. This sets in operation the meteringdevice in theusual way and upon completion ofi ts' metering operation the impulsefrom the battery is through the electromagnet30 will draw the armature29 leasing the latch 25, permitting a further movement of the-coinprojector Bunder gravity to. the cashing in. position shown in Fig. 2,in which position the coins previously held in the compartments of thecoin projector willv pass into the collectingreceptacle 3 1. v Thecontinuation of the movement of the quadrant 61 causes the link 68 toengage the pin after the lost motion has been taken up by the slot 69.The coin projector will thereupon beswung to. the normal position shown.in Fig. 1 andduring its motion the pin 83 will. come into an engagementwith the cam surface 82 thereby locking the quadrant 81 and restoringall parts to the initial position.

Assuming in the second place that call is for any reason ineffective theparts being as shown in Fig. 3, the caller replaces the receiver K onthe hook 7 9, the timing mechanism G is set in operation as previouslydescribed but owing to the call being inefiective no impulse arrivesfrom the metering mechanism and, consequently, the magnet 30 will. notbe energized and the latch 35 will not be released and the coinprojector B will remain in the position shown in Fig. 3 until the lostmotion represent d by the slot 69 is taken up, when the coin projectorreturning to its initial position as previously described will, in thiscase, carry with it the coins in its con'ipartment which, when movedfree irom the projection 23, will pass through the chute 35 anddischarge chute 3G and thus be recovered by the caller.

It will be seen that in both instances the coin is either received orreturned without other action on the part of the caller than taking oiland replacing the receiver from its hook.

The compartment 18 on the coin projector 13 is conveniently used for thecollection of co ns for toll calls and other excess charges under thedirection of an operator.

.iissuining that a connection: has been established to an operator andthe operator desires to collect the excess charge, the operator willinstruct the caller to insert the additional coins, the mechanical partsbeing at thistime in the position shown in Fig. 3.

The additional coin being inserted through appropriate coin slot willpass to the con'ipartm'l'mt 18 and ring the gong 102 or hell 101 and becashed in or be returned in the net. l way as described.

It may be observed that should it be de-.

sired for any purpose to utilize the insertion of the coin as a means ofactuating the coin projector Blhis may be accomplished through theengagement the coin with the pin 80 the motion of the quadrant 81 heiie;connected to the coin projector B through the link 86 and pin and slotconnection already described, thus efi'ecting movement 01 the coinprojector and bringing it into engagementwith the latch 25 alreadydescribed.
